A vehicle heat exchange system includes a coolant circulation circuit, a refrigerant circulation circuit, a pump controller, and a detector. In the coolant circulation circuit, a coolant is circulated. In the refrigerant circulation circuit, a refrigerant is circulated. The pump controller controls a flow rate of the coolant. The detector detects a liquid temperature of the coolant before cooling an electric unit. The coolant circulation circuit includes a radiator that dissipates heat of the coolant having cooled the electric unit. The refrigerant circulation circuit includes an exterior heat exchanger in rear of the radiator. The exterior heat exchanger causes the refrigerant to absorb heat from external air. When the detected liquid temperature is equal to or higher than a predetermined temperature, the pump controller maintains or increases the flow rate. When the detected liquid temperature is lower than the predetermined temperature, the pump controller decreases the flow rate.
